7 Claims. (Cl. 229-37) This invention relates to a carton having anintegral lid at its top, particularly that type of carton or box, usedin packaging commodities which are dispensable from the carton over aperiod of time. For example, cigarettes, cigars, certain candies, andthe like, are carried about in their package and dispensed one or a fewat a time, as distinguished from items which are entirely removed fromtheir packages at one time.

Such cartons serve, then, not only as a package but also as a dispenser,and must be easily openable, give ready access to the contents, be ableto resist crushing and other deformation when carried on the person, andalso providing a tight closure when so carried.

it is a primary object of this invention to provide such a cartonwherein the entire carton, together with its lid, is formed from asingle blank of sheet material, and wherein there is a minimum of wastewhen cutting the carton blanks from a sheet of material.

Another object of the invention is to provide such a carton, includinginner and outer panels forming inner and outer body members, from asingle blank which is easily folded into assembled position, and whichprovides a sturdy carton resistant to deformation.

A further object of this invention is to provide such a carton whereinthe inner and outer members have an integral connection adjacent thebottom of the assembled carton, thereby preventing accidental severanceor removal of the inner member and facilitating manufacture by keepingboth portions at all times in proper orientation.

Additional objects and advantages of the invention will be apparent fromthe following description, the accompanying drawings, and the appendedclaims.

In the drawing Fig. 1 is a plan view of the blank from which the cartonof this invention is formed;

Fig. 2 is another view of the blank of Fig. 1 with the panels of theinner carton member folded over upon the outer carton panels;

Figs. 3 and 4 are views showing the steps of folding the blank of Fig. 2into flat tubular form;

Fig. 5 shows the tubular blank of Fig. 4 in erected conditionpreparatory to folding the end flaps thereof;

Fig. 6 is a vertical section through the assembled carton, with the openposition of the lid shown in dotted lines;

Fig. 7 is a perspective view of the finished carton with the lid open;

Fig. 8 shows a modified carton blank in accordance with the invention;and

Fig. 9 illustrates the blank of Fig. 8 with the panels of the innercarton member folded upon the outer carton panels.

Referring to the drawings, which illustrate preferred embodiments of thepresent invention, and particularly to Fig. l, the blank for the cartonprovided by this invention includes a series of four outer panelslongitudinally arranged with respect to each other and separates PatentD rated by suitable score lines to provide a front panel 10, side panels11 and 12 and'a rear panel 15. Glue flap 16 extends from the free edgeof side panel 11, and is adapted to be fixed to the free edge of rearpanel 15 to complete the main body of the carton, as will presently bedescribed.

The front and side panels are slit along a continuous line 18transversely of fold panel 10 and bias cuts 19 across the side panels 11and 12 respectively, thereby providing upper portions 20 and 21 on thefront and side panels respectively which are separated fiom theremainder of these panels. A transverse score line 25 extends acrossrear panel 15 from the end of bias cut 19, and another score line 26extends across glue flap 16, to be superimposed upon score line 25 inthe assembled carton. Suitable top end flaps 27 are integrally hingedlyconnected to front and side panel portions 20 and 21, and to the top ofrear panel 15, along fold lines 28, and are separated from each other bycuts indicated by solid lines 29.

Another fold line 30 extends across the bottom of the blank, at thelower end of panels 10, 11, 12 and 15,

providing an integral hinged connection for bottom end flaps 32, 33 and34. In addition, an inner front panel 35 having extended connectingportions 36, which in blank form completely surround the bottom end flap32,

is hingedly connected to the outer front panel 10 along the intersectionof these extended portions 36 and panel 19 at fold line 30. The otherend flaps 33 and 34 are separated from each other and from theconnecting portions 36 along cuts indicated by the solid lines 38 inFig. l, and the bottom end flap 32 is separated from connecting portions36 and the adjacent part of inner front panel 35 along out line 39.

The length of inner front panel 35 is such that when it is folded upabout line 30 into superposition upon the inner face of outer frontpanel 14) and its upper portion 20, the free edge of inner front panel35 falls just short of fold line 28. This relation is best seen in Fig.2, wherein the inner front panel has been folded into such position.Inner side panels 40 extend from the opposite side of inner front panel35 and are foldably connected thereto along score lines 41. These innerside panels 40 are superimposed upon outer side panels 11 and 12 whenthe inner front panel is folded up as in Fig. 2, and adhesive, appliedin a transverse strip 44 across the face of inner panels 35 and 40 whichengages outer panels 10, 11 and 12, holds there panels in superimposedrelation, as seen in Fig. 2.

Furthermore, the inner member extends substantially into the lid in itsclosed position, and the upper edges of the connection panels 35 and 40provide corners on the inner member, as seen in Fig. 7, which areengaged by inner surfaces of the front lid portion 20 during opening andclosing movements of the lid. Thus, there is a frictional resistance toopening and closing of the lid and consequently the lid is retained inclosed position unless a force is exerted to move it to open position.

Referring to Figs. 3 and 4, the side panel 11 is folded onto the innerfront panel 35, as seen in Fig. 3, and adhesive is applied to the thenupwardly facing side of glue flap 16. In Fig. 4, the rear panel 15 andits connected end flaps 27 and 35 have been folded over from right toleft'along the fold line connecting panels 12 and 15, and the free edgeof rear panel 15 rests upon and adheres to glue flap 16, thus providinga flattened tubular form of the carton, which is erected into opentubular form as shown in Fig. 5 for closing of the end flaps to providetop and bottom walls.

Referring to Fig. 5, the carton is shown in erected tubular form, andthe bottom end flaps 33 have begun to swing inwardly across the bottomof the open tubular form. When these flaps 33 extend across the bottomof the carton the end flap 32 is folded downwardly upon them, asindicated by arrow 45, and finally the lower end fla 34 is foldedupwardly. andzadhered toflap 32,- in the direction indicated by mower,incomplete thelhottom wall which is shown generallyjat 47 in Fig.6. Atop wall dsiis lthen formed indike manner, withlthe top .end

flaps folding'inwardly first in the direction indicatedby arrows 56, andthen in sequence, first by the arrow 51, and then by the arrow 52."These top end flaps are secured together by :suitable adhesive to formthe finished top wall 43. j i V 1 The finished carton, shown in sectionin Fig. 6 and in perspective inFigpT, includes an inner memberprovided'by' inner front panel 35 and inner side panels and an outerormain body member provided by front panel 10,;side panels 11 and12, andrear panel 15. The upper portions 20 and,21; of, the outer member, beingseparated therefromalong'slits v18, 19 provide, in cc,

operation with the top wall'48, .a lid which .is hinged about score line25, and movable between an open posi 'tion indicated in dotted lines inFig. 6, and the closed position shown in full lines. -If desired,theupper rear corner of inner side panels 40 may be rounded as at 55 toIfacilitatethe opening and closingiof thelid; 7 .Referring to Figs.fixand 9, there is shown a carton blank similar to that of Figs. 1 and2, and like parts are indicated by'liketreference numerals. In themodification of FigsQS'and 9, however, the inner member is prosequenceof'assembling'the blank shown in Fig. 9 is' exactly the same as theprocedure above described in connection with Figs. 3, 4 andS. i

The present invention thus provides a carton having an integral lidthereon which is formed from a single compact blank, and which, due toits double-walled construction, is liighlyresistant to crushing or otherdeformation. This carton is 'inexpensive'to manufacture, simple toassemble, and affords more than adequateprotection for the commoditiesto be packaged therein.
